A bag o' tricks from the Perlmeister

Write Down Everything

Often, a developer stumbles across ugly code constructs such as duplications or obvious bugs that output ugly warnings at run time. Then, a small distraction happens, such as the discovery of even more catastrophic failures that must be resolved immediately or a work disruption in the form of a meeting with the boss – and the previously discovered error falls through the cracks. Nothing is more annoying than to see errors that you already discovered pop up later during a live demo or in production, because you let them slip through.

Therefore, make a note of everything, either in a note system such as Evernote or, if you have the discipline to repeatedly look for to-do tags in your code, with such keywords. Beware, however; many developers never actually look for these later, as is evident by many an open source module that contains forgotten to-do constructs, even if the code has seen years of production. Automatic search as part of the release process makes sure the cleanup actually happens later.

  • Perl: CPAN Additions

    Many people have declared the granddaddy of scripting, Perl, to be dead. A look at new items in the CPAN software repository, however, shows that the community is still quite active.

  • Perl: Testing Modules with Docker

    If you want to distribute your programs across multiple platforms, you need to prepare them to run in foreign environments from the start. Linux container technology and the resource-conserving Docker project let you test your own Perl modules on several Linux distributions in one fell swoop.

  • Perl: Travis CI

    A new service on travis-ci.org picks up GitHub projects, runs new code through test suites, and notifies the owners if the build fails. Its API enables Perl scripts to gather historical build data, including who-broke-the-build tabulations.

  • Perl: Cucumber

    The Cucumber test framework helps developers and product departments jointly formulate test cases, not as program code, but in plain English. The initially skeptical Perlmeister has acquired a taste for this.
